Description of the job :
With the development of high and ultra-high bypass ratio turbofans, engine and airframe are strongly coupled and the exhaust jet interacts significantly with the wing and flaps. This coupling results in jet-airframe interaction noise as one of the main noise sources at takeoff.
Airbus needs to evaluate jet noise and jet-airframe interaction noise sources with account of highly three-dimensional engine exhaust and integrated powerplant-airframe architectures. While compressible Navier-Stokes flow solvers offer solutions to compute directly noise sources at a certain expense, this study will focus on faster-return tools.

Task & accountabilities :
The aim of the PhD is to model both noise sources (jet noise and jet-airframe interaction noise) and their propagation based on a mean flow.

One of the challenges will be the development of strategies to compute three-dimensional jet instabilities and extract practical models for organized jet noise sources.

For this, the PhD candidate will understand, use and improve existing tools for flow stability analysis, noise source models and propagators such as analytical tailored Green’s functions and numerical Boundary Element Method.

The developed methodology will be validated against laboratory experiments to be performed in the same time frame as the study. Furthermore the method will be applied to realistic applications.

Required skills :
To be able to carry out this thesis, it is essential to have an advanced level and the following qualities:

- Very solid knowledge in Flow Dynamics and Aero acoustics.
- Good knowledge in computer programming (Linux, Python, Matlab)
- Good level in English and French.
- Soft skills: autonomy, curiosity, motivation, communication, team spirit.

This job requires an awareness of any potential compliance risks and a commitment to act with integrity, as the foundation for the Company’s success, reputation and sustainable growth.
